I wanted to get everyones opinion.  I want to refinish the upper, lower, and barrel of my AR-10 OD green.  I am not sure what is the best finish for me, I want something very durable and thin preferably applied after blasting.  I also would prefer to send it off to have the work done.  I was planning on sending it to Wilson Combat for their Tuff Coat but was told they are too backed up to do it.  What would you guys do?
